Specification of Letters Patent.

Application filed April 18, 1911.

Patented May 12, 1914.

Serial No. 621,797.

Referring to the drawings, wherein similar reference numerals designatelike parts throughout the several views, 1 indicates the dashboard, 2the hood, 3 the radiator and 4 the gasolene engine of a motor vehicle.

My improved starting device is secured to the engine cylinders by meansof brackets 6 each comprising a vertical portion 48 fastened to thecylinders at 4:9, by means of bolts, and terminating at its upper end ina forked arm 50 provided with bolt holes alining with openings in thevalve casing 10 of the starting device, whereby the brackets may berigidly secured to the casing.

My improved starting device comprehends a gasolene tank or reservoir 7,an air pump 8, a combined cut-oil and distributing valve 9, and a valvecasing 10 provided with passages 17 for conveying the motive fluid to acombined mixing and pressure chamber 12, wherein the motive fluid isprepared and forced into the engine cylinder through suitable conduits.The tank or reservoir 7 is provided with the usual filling opening 13and outlet conduit 14 said conduit leading to the valve 9 in the casing10. The valve 9 comprises a tapering body formed with a chamber 15, oneend of said chamber being closed by a wall formed integral with the bodyand having a squared portion 46, pro jecting therefrom for the purposeof receiving a valve operating lever 43. The 0pposite end of the chamber15 is closed by a plug 44, said plug being screw threaded into the bodyof the valve to permit of its removal when it is desired to gain accessto the interior of the chamber 15 for cleaning or other purposes. Theoutlet conduit 14 of the tank 7 communicates with valve 9 through a port45, said port being normally open to the conduit. Outlet ports 16, areformed in the valve, at an angle between 45 and. 90 degrees to the port45, the number of said ports depending upon the number of cylinders ofwhich the engine is composed, four cylinders being shown inthe drawing.The valve casing 11.0 is provided with passages 17 leading from thevalve 9 to a combined mixing and pressure chamber 12. The chamber 18 islocated at the bottom of the valve casing 10 and extends longitudinallythereof and is provided with discharge nozzles in the form of nipples 19connected by means of packing nuts 20 to the conduits- 21. The conduits21 are composed of short lengths of piping and lead to the enginecylinders and are connected thereto by means of the spark plugs. Thespark plugs for this purpose constitute a combined sparking and primingplug of any well known structure. The conduits 21 are provided withcheck valves 22 adapted to open under pressure of the mixture beingforced into the cylinders and to prevent such mixture from hacking intothe conduits upon the explosion of such mixture.

Brackets 23 are formed on the upper surface of the casing 10 and areadapted to receive and securely hold the air pump 8. The pump comprisesthe usual cylinder 24, piston 25 and piston rod 26 which rod is providedwith an operating handle 28. The cylinder is provided with front andrear heads 29 and 30 respectively. The rear cylinder head 30 in additionto the usual air intake port 32, is provided with a stationary electriccontact block 34, insulated from said head and connected with theignition mechanism at any suitable point by means of a conductor 35. Aport 41 formed'in said cylinder head 30 leads from the interior of thepump cylinder to the chamber 12 and communicates therewith by means of ashort section of piping 42, whereby the air from the pump cylinder maybe forced into the chamber 12, for the purpose of mixing the air'withthe gasolene and forcing the same into the engine cylinders through theconduits 21. The front head 29 is provided with a laterally projectinglug 31 adapted to carry a combined valve and spark operating rod 36. Thesaid rod 36 is rigidly connected to the operating rod of the pump pistonfor simultaneous operation therewith. This connection is made throughthe medium of an arm 51 preferably formed integral with the rod 36, andrigidly secured to the pump operating rod by means of a set screw 37. Inits normal position the pump piston is midway the ends of the cylinderand is held in such position 'by means of a spring 38. The said spring38 encircles the operating rod 27, and one end thereof engages thecylinder head 29, and the opposite end engages the arm 51 of the rod 36.The rear end of the rod 36 carries an electric contact block 39 adaptedto contact with the block on the rear cylinder head 30 and thereby makeand break the electric circuit leading to the spark plugs. The saidblock 39 is adjustable along the length of the rod 36 and is held in itsadjusted position by means of a set screw 40,-the purpose of thisadjustment is to enable the sparking apparatus to be operated at anydesirable point relative to the length of stroke of the piston 25.

bearing connection with said cap nut as indicated at 4E7. This method ofsecuring vthe valve in place. provides means for taking up any wear onthe valve or casing due to the oscillating motion of the valve, and atthe same time enables the valve to operate freely within the casing.portion of the piston rod 26 and the operating handle 28 project throughthe dash 1 of the vehiclefwhereby the device is placed within convenientreach of the operator.

The operation of my improved starting device may be stated to be asfollows :By

the force of gravity the 'gasolene in the tank 7 is discharged into thechamber 15 of the valve 9 through the conduit 14c and port 45 of saidvalve, said port in its normal position being in communication with theconduit the chamber 15 is therefore charged with gasolene. Upon pullingthe handle 28 of the piston air is drawn into the cylinder through theport 32, and the rod 36 is simultaneously operated with and by thepiston to cause the rear wall of the slot &2 to engage the valve lever43 causing said lever to assume the position indicated in dotted linesin Fig. 1, in which position the valve 9 is out of communication withthe gasolene tank and the ports 16 of said valve coincide with thepassages 17 of the valve casing whereby the gasolene contained in thechamber 15 of the valveis discharged through said passages 17 into thechamber 18. On the return stroke of the piston the valve 9 is cut offfrom communication with the passages 17, by means of the front wall ofsaid slot 42 engaging the valve lever 43, and the air which waspreviously drawn into the pump cylinder is discharged into the chamber18 through the conduit 42, whereby the gasolene within the chamber 18 iscaused to mix with the inrushing air and by the action of the same isforced through the conduit 21 into the engine cylinders. When the pumppiston has completed its stroke the contact block 39, carried on thelever 36, engages the block 34, carried by the rear head of the pumpcylinder, and thereby completes the circuit to the spark plugs, causingan explosion of the mixture within the cylinders and thereby startingthe engine. Upon releasing the pump handle 28, the spring 38 causes thepump to assume its normal: position, breaking the circuit at the contactblocks and placing the device in position for another ope 'ation.
